Product Description
Brief Introduction.
This series pressure reducing valve is a new type regulating valve which adopts piston to replace the diaphragm. The performance is reliable and it's can be used for a long time. The down pressure can be adjusted according to the requirement, and it can be set at a fixed pressure in the application, which won't be changed as the fluctuation of the up pressure and the flowing rate.
Field of Application.
Pressure Rating: 1.0- 6.4Mpa
Nominal Diameter: DN20-400
Body Material: Steel, CF8
Standard flanges: DIN, ANSI, JIS.
